【Abstract】 The acidic basic property of hydrated oxides was characterized by the effective static potential Z * /r of the center ions and the drawing of Z * /r -Z (atomic number) has been made. The known regularity of the acidic basic property of hydrated oxides can be seen from the drawing simply and directly. Moreover, it has also been discovered that hydrated oxides with Z * /r above 6.7 are acids, that with Z * /r below 5.0 bases, and that with Z * /r between 6.7 to 5.0 amphoteric substances. This result coincides with the fact.更多还原
